Patented Dec. 17, 195+,

To all whom it may concern:

Be it known that I, EMIL GERBERT, a subj ect of the German Emperor,residing at Waltershausen, Duchy of Saxe Coburg- Gotha, Germ an Empire,have invented certain new and Useful Improvements in Means-for AttachingTires to VehicleJlVheels, of which the following is a specification. gThis invention relates to means forattaching tires to vehicle-wheels.

The method of attaching metal rimswith india-rubber tires vulcanizedthereon'to the fellies of carriage or cart-wheels by pressure, 1 splinesor wedges has-the disadvantage that t e tires are not firmlysecured andtherefore soon begin to slip or creep on thefellies. The tires are thussubjected to considerable damage and soon becomewornout. Thisdisadvantage isobviated by the present invention which consists inprovidingat one side'of the metal rim a number of projections adapted toengage corresponding I recesses adjacent the rubber tire, axialdisplacement of the latter being prevented by the said a ring screwed tothe felly on the-other side. I The invention is illustrated in theannexed drawing by means of .an example in connection with a solidindia-rubber tire at-' tached by vulcanization to a metal rim.

Figure 1 is a side-view, in which a portion of'the tire and rim areshown detached. Fig.

'cross-secti0ns on the lines AB and CD of, Fig. 1 respectively.

The felly '1 is provided with having recesses 2, and the tire rim 6 areso placed on the felly the flange 3 4 and metal" that the projections5of said rim enter the recesses 2'and thus'prevent creeping of the tireon the fel'ly.

and 4 are on the felly is revented by'the rings screwed to-the fe 1y at7, the screw-threads used being preferably square. v

For so'-c'alled twintires mounted cated between'the tires, witht e metalrims Yof'the latter engaging alternate recesses in the flange. I

What I claim as. my'iinve ntion and desire to secure by Letters Patentof. the United' States-is:.

1. In a vehicle wheel having cumferential flange: on said fe l a felly,a ciry and having spaced recesses,.a rim carried by the felly and havinglateralprojections' at one edge.

for engagement in the recesses, a tire supported by the rim, and screwthreaded-means? for engagement with the felly on the s de on adouble-felly, the flange 3' isreferably lo- Axial displacement of thetire and'metal rimopposite the flange for maintaining the rim sai felly;p

2. In combination'with avehicle wheel having a felly, of a'flange havingspaced re'- osition against lateral displacement on cessescircumferentiallyarranged, on said felly at one edge thereof, saidvfelly provided withscrew threads at'the opposite edge, a

rim for supporting a' tire mounted on said telly-and having edgeprojections at one side' for engagement, in the recesses,- and a screwthreaded member for engagement with the screw threads in the telly tolock said rim against lateral dis lacement onsaid felly.

In testimony w ereof I have hereunto set my'hand in presence of twosubscribing Witnesses. T
